Application The CT-S range timers are designed for use in industrial applications. They operate over an universal range of supply voltages and a large time delay range, within compact dimensions. The easy-to-set front-face potentiometers, with direct reading scales, provide accurate time delay adjustment. Operating mode The CT-ERS.12 with 1 c/o contact offers 10 time ranges, from 0.05 s - 300 h, for the adjustment of the time delay. The time delay range is rotary switch selectable. The fine adjustment of the time delay is made via an internal potentiometer, with a direct reading scale, on the front of the unit. Timing is displayed by a flashing green LED labelled U/T. Function diagram Remarks Legend: G Control supply voltage not applied / Output contact open B Control supply voltage applied / Output contact closed Terminal designations on the device and in the diagrams: The c/o contact is designated 15-16/18. Control supply voltage is applied to terminals A1-A2. Function of the yellow LED: The yellow LED R glows as soon as the output relays energize and turns off when the output relays de-energize. A ON-delay This function requires continuous control supply voltage for timing. Timing begins when control supply voltage is applied. The green LED flashes during timing. When the selected time delay is complete, the output relay energizes and the flashing green LED turns steady. If control supply voltage is interrupted, the output relay de-energizes and the time delay is reset.
